Have any of you experienced slight cracking on any of your Chanel bags that is patent leather? I recently just got an extra mini flap the other day and noticed that there was slight cracking on the stitching where the bag folds over. It's not noticeable until you closely inspect it. Any help or suggestions? Should I be worry about it and return it? Or just keep the gorgeous gem? I hate to send it back...Granted, I ordered it via phone and had it shipped out to me. Thank you!!
